Abstract
We have measured the near-edge x-ray-absorption fine-structure spectra of the K edge of potassium in the polymer-salt complex poly(ethylene oxide)-KI. Changes are observed as a function of temperature due to modifications of the K-ion coordination. Comparison with model systems suggests that the lower activation energy of this ionic conducting polymer complex at elevated temperature (T>70 °C) is partially due to reduced oxygen complexation of the K ions.Keywords
